Experiencing pubic bone pain in your third trimester can be quite common, and for many, it's when Symphysis Pubis Dysfunction (SPD) truly makes its presence known. This discomfort, sometimes called 'pubic-bone pelvic pain,' stems from the softening and increased mobility of the joints in your pelvis, particularly the symphysis pubis at the front.
Why it shows up this trimester
As you move into your third trimester, your body is preparing for birth. The hormone relaxin continues to soften ligaments, and your growing baby is getting heavier. A significant factor in this window is when your baby's head begins to 'drop' or engage into your pelvis. This shifting weight and pressure can put additional strain on your already softened pubic joint, intensifying the sensations of SPD. Your center of gravity also continues to shift, which can alter your gait and posture, contributing to the discomfort.
